Quintus (Immortals of New Orleans, Book 9). Immortals of New Orleans, #12

After a brutal attack forces him back to New Orleans, Quintus Tullius finds himself drawn into a conflict that reaches far beyond vampire law. Ancient, lethal, and bound by duty, he has spent centuries concealing the full extent of his power. When an unexpected stranger saves his life, Quintus realizes she is far more dangerous than she appears. Gabriella Savoie has been running since childhood, hiding her abilities from a coven determined to destroy her.
Survival has taught her secrecy, restraint, and how to stay one step ahead of those who hunt her. Crossing paths with Quintus places her directly in the path of a world she has spent her life avoiding. As threats rise from Louisiana to New York, Quintus and Gabriella find themselves bound by circumstance, their survival tied to a fragile alliance neither planned. Searching for an artifact that could shift the balance of power, they are drawn closer with every step, resisting an attraction that threatens to blur every line Quintus has sworn to uphold.
With immortal politics tightening their grip and enemies closing ranks, trust becomes both a risk and a weapon. Quintus must decide whether following the rules will cost him the woman who has changed everything. Quintus is a paranormal romance novel in the Immortals of New Orleans series.
